CYCLOMETER.

SPECIFICATION forming part of Letters Patent No. 481,608, dated August 30, 1892. Application filed April l5, 1891. Serial No. 388,993. (No model.)

To @ZZ whom t may concern.'

Be it known that I, FRANK C. WESTON, a citizen of the United States, residing at Bangor, in the county of Penobscot and State of Maine, have invented a new and useful Improvement in Cyclometers, of which the following is a full, clear, and exact description, reference being had to the following drawings, forming a part of this specification, in explaining its nature.

Theinvention relates, primarily, to a cyclonieter adapted to be fastened to the frame of a bicycle or tricycle, and preferably with its dial upward or in a position to be read bythe rider when in his saddle, and which is actuated by one of the wheels of the machine or by some moving part thereof.

It further consists in various features of construction, organization, and application, reference to which will hereinafter be made.

In the drawings, Figure l is a view in plan of the cyclorneter attached to one fork of a bicycle. Fig. 2 is a det-ail view in elevation to represent the relation between the cyclometer, fork, and wheel. Fig. 3 is a plan View 0f the cyclonieter, the dial being removed. Fig. 4 is a vertical section through the case, the works being removed.

The cyclometer is represented in the drawings as applied to a bicycle, and it is shown as attached to the front fork of the machine. The cyelometer is represented as consisting of a ease A, preferably of metal, and a train of gears contained in the case and actuated by a tappet or projection c upon the spoke d 0f the wheel a2, acting through the oscillating arm or lever l) at the lower end of the shaft b. The case A has upon one side a clamp c of any desired form, by means of which it is attached to the fork or other part of the bicycle. The clamp shown in the drawings has the two sections c', one or both of which may be yielding and the ends of which are adapted to be brought together and held by a screw c2, passing through holes in the outer ends of the sections and the nut c3. The oscillating arm or lever b communicates motion to the registering devices through the shaft b by means of a spring-pawl h2, carried upon a plate b3 in the case A. and secured to the upper end of the said shaft. This pawlis pivoted to the plate b3 at b4. Its end h5 engages when it is moved in one direction with the ratchet-wheel hmounted upon the stud lf. A spring o8, carried by the plate h3, bears against the end b5 and holds the end b9 of the pawl in engagement with the pin Z910. This pin is so placed that it maintains the forward end of the pawlin contact witha tooth of thewheel h6 when moving in one direction, and thereby causes the wheel to be turned a portion of a revolution. Upon the backward or reverse movement of the plate Zand of the pawl the spring bs yields sufiiciently to permit the pawl to clear the teeth of the wheel be. The wheel b6 has a pin projecting downward from its under surface and which at every full revolution of the wheel comes into contact with a tooth of the wheel d. This wheel is mounted upon a stud cl2 and has a long sleeve cl3 extending above the dial D and carrying the indicator-hand d". This wheel communicates movement to the wheel E upon the stud e by means of a piu c2, projecting upward from the wheel Cl. This wheel E has a sleeve e3, which projects upward above the dial and carries the indicator et. The wheel E is in turn connected with the wheel F by means of the pin e5, the said pin engaging a notch of the wheel F every rotation of the wheel E. The wheel F is mounted upon the stud f and has a sleeve f extending above the dial and carrying the indicator f2. The wheel F is connected with the last wheel G of the train by means of the pin f3, which engages a tooth of the wheel G every revolution of the wheel F. The wheel G is mounted upon the stud g and has a sleeve gextending above the dial and carrying an indicator g2.

There may be detent-pawls for various of the wheels, and l have represented the wheels b and E as provided with the detent-pawls 7L and 7L', formed from or upon a single strip h2 of thin metal held bythe stud h3 at the center of its length. The strip is represented as bowed or curved upon each side of the pivot and as having its engaging ends formed by bending the ends very nearly to a right angle. Similar detents h3 and 7L* are provided for the wheels F and G by a similar bent strip of metal fastened to the case by the stud h5. While l have referred to the studs as being IOO carried by the case, I would say that they may be mounted upon a separate plate adapted to be set in the case and to be removable from it..

Vith the organization shown in thedrawings the Wheels d E F G are adapted to be turned as follows: the wheel d and its indicator to make one full revolution for every mile run; the wheel E and its indicator, one full revolution for every ten miles run; the wheel F, one full revolution for every hundred miles run, and the Wheel G one full revolution for every thousand miles run. The dial D is correspondingly marked-that is, the indications for the indicator d4 show quarters of miles or any other subdivisions of a mile desired. The indications for the other indicator-hands represent in their 'respective order mile-divisions, ten mile divisions, and onehundred-mile divisions.

lVith thetrain connected as above described the indicator-hands of two wheels will rotate in a direction opposite that of the indicatorhands of the other two wheels. They may be made to turn in the same direction by interposing gears between the various wheels.

The tappet or projection ais shown as coinprising a piece of metal, rubber, or othersuitable material a3, removably secured to the spoke a by a clamp at. This clamp has the opening a5, by which it is placed upon aspoke, being of a width to receive a spoke, and the set-screw a6, which locks the clamp and the tappet to the spoke. (See Figs. 2 and 3.) This also permits the tappet to be adjustable upon the spoke longitudinally.

In operation the rotation of the wheel causes the tappet or projection a to strike the arinb and turn it sufficiently to move the pawl h4 and actuate the registering mechanism. Af-

ter the tappet has cleared the arm Z1 it is automatically returned to its original position by means of a spring. This spring is represented as applied to the form of construction above specified by means of a flat spring m, fastened at its end fm and bearing against the straight edge m2 of the pawl-plate b3. (See Fig. 3.)

By attaching the cyclometer to the frame of the bicycle or tricycle and by causing it to be actuated by a moving` part of the machine several important advantages are obtained. First, it can be so located as to be easily read while the machine is in motion; second, a much cheaper and simpler construction of cyclometer can be used than where the cyclometer is attached to the wheel to rotate with it, as in the ordinary construction.

Having thus fully described my invention, I desire to secure by Letters Patent of the United States- In a cyclometer, the combination, with the case A, adapted to be attached to the fork of a bicycle or tricycle, of the shaft h, provided With the arm Z) and with the oscillating plate b3, having a flattened side, the springm, bearing against said flattened side, the springpressed pawl h2, carried by said plate, the ratchet-Wheel engaged by said pawl, a registering-train operated by said ratchet-wheel, and the adjustable and removable tappet a, clamped to a spoke of the machine-wheel and arranged to engage the said arm b to operate the cyclometer positively, substantially as set forth.
